TEA2028B

The TEA2028B is designed as one kind of bipolar integrated circuit intended to drive displays, triacs and relays and small stepper motors. The data is serially shifted into the device and is stored in 13 latches that drive the outputs.

Features of the TEA2028B are:(1)TTL and CMOS compatible inputs;(2)outputs drive load in both directions;(3)power-on reset makes outputs floating;(4)wide supply voltage range. And the quick reference data of this device are:(1)supply voltage range: 4.5 to 18 V;(2)output current, each output: 80 mA;(3)clock frequency: 50 kHz;(4)operating ambient temperature range: 0 to +80 .

The absolute maximum ratings of the TEA2028B can be summarized as:(1)supply voltage: 18 V;(2)input voltage range, all inputs: -0.3 to Vcc+0.3 V;(3)output current, all outputs (high): 150 mA;(4)output current, all outputs (low): 150 mA;(5)total power dissipation: 1.4 W;(6)storage temperature range: -40 to +150 ;(7)operating ambient temperature range: 0 to +80 .
